About TOTP
TOTP makes the six-digit code of a two-factor app. It combines a shared secret with the current time, so the code changes every 30 seconds.
Give a Base32 secret or a full otpauth:// URI. The tool shows the current code and the seconds until the next code. Use it to test a login flow or to check that your server and your app agree.
The clock of the server and the clock of the device must agree. Most of the failures of TOTP come from a clock that has drifted, and not from a wrong secret. Do not put a real production secret into any web tool.
